v0.8:

• Updated to .NET 6.0, and thus now requires the .NET 6.0 runtime.
• Improved handling of gzipped input files, so there's no need to extract them first.
• Improved performance of multi-language builds.
• Support for <language>_arcade_data.dat and <language>_license_data.dat files.
• Checks the size of output <language>_gtmode_data.dat and <language>_unistrdb.dat files and throws an error if they are larger than the game can handle (800KB and 24KB respectively).
• Added support for an _Overrides directory to handle language-specific files in a multi-language build. A sub-directory matching the language name will be checked before the base directory for any files, e.g. files in \_Overrides\usa\Event\ will replace files in \Event\ for the usa language only.

Some field mappings have also been updated:

Chassis:
CentreOfMassLongitudinal -> FrontWeightDistribution
CentreOfMassHeight -> Wheelbase

Event:
Unknown5 -> TrackBannerPool

TireForceVol:
GutterGrip -> GuideGrip
GrassGrip -> GreenGrip
WetGripMaybe -> WaterGripMaybe

CarUnknown:
Renamed to Wheel and partially mapped

Gear:
Ratios are now signed, -1 as the default instead of 255

Engine:
Torque curve values are now signed, -1 as the default instead of 255
Displacement is now correctly converted, supports x2 and x3 suffixes for rotaries and twin engines
